Obesity is a common problem among women of reproductive age. Overweight is known to negatively affect a woman’s fertility. So, women of reproductive age who are obese may experience menstrual irregularities, endometrial pathology and, ultimately, infertility. The pathogenetic mechanisms of reproductive dysfunction in obesity remain actively studied issues. It was established that leptin synthesized by adipose tissue inhibits granulosis, cell steroidogenesis and interferes with the ovulation process, which can directly affect reproductive function. Insulin resistance and compensatory hyperinsulinemia, which accompany obesity in women, can contribute to menstrual irregularities, ovulation and, ultimately, fertility. Obesity is also characterized by a state of «relative functional hyperandrogenism», which can affect ovarian function, contributing to the development of infertility. Moreover, obesity is characterized by a state of hyposomatotropinism, which can affect fertility, through changes in ovarian and endometrial function. Weight loss is most likely able to restore fertility in most cases, but there are no practical guidelines that would help the clinician choose the best method to reduce body weight from increased physical activity, dietary restrictions, drug therapy and bariatric surgery.

Recently, it has been noticed a great number of uterine fibroids in women with unrealized reproductive function; moreover, the number of combined forms of hyperplastic processes of the reproductive system in 20-25% of women under 30 years of age and 60% of women over 40 years of age is constantly growing creating a favourable background for cancer. It is also known that women with hyperplastic processes suffer from psycho-emotional disorders both before surgeries and after surgical recovery; many of them are diagnosed with adjustment disorder. As many researches note, the main psychotherapeutic aspects include passive view of life, increased anxiety, tendency to dependent behaviour, rejection of own body, protective behaviour and problems with self-assessment. It should also be noted that a comprehensive study of clinical and laboratory data and subjective criteria of life quality is essential in assessment of the feasibility of hysterectomy in women of reproductive age, even if they do not plan to bear children in the future. The objective of the research was to estimate life quality as well as to improve the system of dispensary observation and rehabilitation of women who underwent uterine surgery.Materials and methods. There was performed a comprehensive examination and surgical treatment of 60 women of reproductive age with uterine fibroid who underwent hysterectomy with preservation of appendages. We used modern high quality endocrinological and instrumental techniques. The assessment of the received data was made immediately after surgery, 6 and 2 months, 3 and 5 years after surgery. Quality of life was studied on the basis of a comprehensive assessment using the modified scale of the Nottingham Health Profile and the study of such important indicators as energy, sleep, emotional reactions, social isolation, physical activity, pain. All statistical analysis was performed using a standard package “Statistica for Windows – 6.0”.Results and discussion. On the basis of anamnestic data of patients we revealed health deterioration with high rates of liver and gastrointestinal tract disorders, metabolic disturbances (obesity, hypertensive disorders, fibrocystic breast disease), metabolic-endocrine changes and surgery. Reproductive health in women with uterine fibroid was characterized by long establishment of regular menstrual cycle, its breach in the period of puberty, inflammatory diseases of the genital organs, benign ovarian tumours and their surgical removal, inadequate reproductive behaviour with absent or delayed implementation of reproductive function and induced abortion. 12 months and especially 5 years after surgery there was noticed a progressive deterioration of the ovarian function, which was reflected as the reduction in their volume due to the reduction in the number and size of follicles, deterioration of blood supply to the ovaries, decreased blood flow in the internal iliac artery basin. It should also be noted the progressive hypestrogenism; in addition, there was a clear correlation with the age of the woman, who underwent surgical operation. Changes in life quality of patients with hyperplastic processes of the uterus were manifested in the postoperative period as follows: a decrease in physical activity (43.33% of cases), increased sexual dysfunction (36.66%), inhibition of mental state, conflict-orientated social behaviour, weakening of role functions and subjective deterioration of health and life quality (51.66% of cases).Conclusions. Thus, surgery on uterine fibroids with total or subtotal hysterectomy contributes to interference in a complex neuroendocrine interaction between hypothalamus, pituitary, ovaries, adrenal cortex, thyroid gland and affects the blood supply, innervation, and lymph efflux in the pelvic floor; therefore, postoperative syndromes are polyglandular and polysystemic. Long-term effects after surgery are accompanied by progressive hypestrogenism, decrease in the ovarian function (the reduction in their volume observed during ultrasound examination), reduction in the number and size of follicles, deterioration of blood supply to the ovaries, low blood supply to the internal iliac artery basin.

The prevalence of overweight and obesity among women in Uzbekistan is 31.7 %. There is an annual increase in people with obesity. The facts of the negative impact of fat mass on the hormonal system and, as a result, a decrease in fertility in women are not in doubt. The purpose of this study was to evaluate the results of Metformin use in overweight and obese women of reproductive age. The study included 45 women of reproductive age who could not reduce weight with diet therapy. All patients were divided into three groups: group 1-planning pregnancy (n = 15), group 2 – having abnormal weight gain after childbirth (n = 15), group 3 – having overweight and obesity not related to pregnancy and childbirth (n = 15). Weight loss while taking Metformin increases fertility and should be performed in obese women as pre-gravidar training.

Abstract The prevalence of obesity in adults worldwide, and specifically in women of reproductive age, is concerning given the risks to fertility posed by the increased risk of type 2 diabetes, metabolic syndrome and other non-communicable diseases. Obesity has a multi-systemic impact in female physiology that is characterized by the presence of oxidative stress, lipotoxicity, and the activation of pro-inflammatory pathways, inducing tissue-specific insulin resistance and ultimately conducive to abnormal ovarian function. A higher body mass is linked to Polycystic Ovary Syndrome, dysregulated menstrual cycles, anovulation, and longer time to pregnancy, even in ovulatory women. In the context of ART, compared to women of normal BMI, obese women have worse outcomes in every step of their journey, resulting in reduced success measured as live birth rate. Even after pregnancy is achieved, obese women have a higher chance of miscarriage, gestational diabetes, pregnancy complications, birth defects, and most worryingly, a higher risk of stillbirth and neonatal death. The potential for compounding effects of ART on pregnancy complications and infant morbidities in obese women has not been studied. There is still much debate in the field on whether these poorer outcomes are mainly driven by defects in oocyte quality, abnormal embryo development or an unaccommodating uterine environment, however the clinical evidence to date suggests a combination of all three are responsible. Animal models of maternal obesity shed light on the mechanisms underlaying the effects of obesity on the peri-conception environment, with recent findings pointing to lipotoxicity in the ovarian environment as a key driver of defects in oocytes that have not only reduced developmental competence but long-lasting effects in offspring health.

Polycystic ovary syndrome (PCOS) is a common cause of ovulatory dysfunction affecting women of reproductive age. Obesity and insulin resistance are thought to potentiate disruptions in antral follicle development that result in chronic anovulation, and as such, have become important therapeutic targets of dietary interventions aimed at weight loss. Caloric restriction has been shown to promote sporadic ovulation in obese women with PCOS, but improvements have occurred across a wide range of patients and little has been garnered about the factors that distinguish responders from non-responders. Further, few studies have evaluated the likelihood for modest weight loss to restore normal ovulatory cyclicity in PCOS. Consensus regarding the impact of dietary intervention on ovulation has been limited by variability in the measures used to characterize and report ovulatory status across studies. In response, this review provides an assessment of the evidence surrounding the effectiveness of hypocaloric dietary intervention to normalize ovulatory function in PCOS. The impact of physiological vs methodological factors on the evaluation of ovulatory status is discussed, and recommendations to strengthen future studies in this area are provided. Ultimately, further research is needed to understand the optimal dietary or lifestyle approaches that promote ovulation and sustained improvements in reproductive function in PCOS.

Introduction. Analysis of uterine leiomyoma incidence indicates not only its growth but also the increase in the number of women of early reproductive age. However, the problem of trigger mechanisms for its development is still uncertain and actual.The objective of the research was to assess the characteristic features of hyperplastic processes in uterus on the background of dishormonal and metabolic disorders.Materials and methods. 60 women of reproductive age with uterine leiomyoma participated in the clinical trial. They gave their informed written consent. The control group consisted of 20 healthy women of reproductive age. Statistical analysis was conducted using material package “STATISTICA for Windows®-6.0” and methods of odds ratio (OR) calculating and its 95% Confidential Interval (95% CI).Results and their discussion. According to the results of the research the main factors contributing to uterine fibroid development in women with obesity were determined. They included: the age of 30-45 years, instrumental intervention in the womb (abortion, diagnostic curettage, etc. (OR = 8.2; 95% CI: 5.1-13.5)); chronic inflammatory diseases of genitalia (OR = 7.9; 2.9-21.9); hormonal imbalances (fibro-cystic breast disease, thyroid disorders (OR = 8.61; 3.1-23.8), liver and gastrointestinal tract disorders (OR = 5.8; 2.1-15.9) sexual disorders and stress inductive factors (OR = 2.6; 1.4-7.1) (usually fibroids occur in 1-2 years after severe stress). There is a significant percentage of adenomyosis and endometrial hyperplastic processes. Growth of tumors in women with obesity increases to 35-40 years of age, and is associated not only with a progressive decrease in the functional activity of the ovaries, their sensitivity to gonadotrophic stimulation, but also with chronic functional exertion of regulation systems on the background of metabolic disorders of hemostasis and homeostasis in this category of women.Conclusions. One of the most significant risk factors for hyperplastic processes of the reproductive organs is obesity and associated metabolic disorders. In case of metabolic disorders activity and hepatocytes on the background of obesity the number of combined forms of hyperplastic processes in the uterus increases by 1.9 times. The main risk factor for fibroids in obese women is hepatocytes dysfunction on the background of a high percentage of hepatobiliary pathology, endocrine pathology – 68.3% (thyroid dysfunction, fibro-cystic breast changes). Morphological and histological structure of endometrium in obese women leads to the growth of endometrial polyps (36.66%).

PCOD can be managed with Ayurvedic diet. Ovarian Syndrome is one of the most common female endocrine disorders affecting approximately 5% to 10% of women of reproductive age and is thought to be one of theleading causes of female sub-fertility. The symptoms of PCOS may begin in adolescence with menstrual irregularities, infertility, high levels of masculinising hormones, metabolic syndromes.In Ayurveda, this condition is not explained as a single disease, but can be  under the headings of Yonivyapad and Artavadushti. In this study, elementary books of Ayurveda and modern were searched and analyzed for proper utilization in prevention and cure of PCOS. PCOS is an emerging problem among women leading to endocrine dysfunction.Treatment modalities aim at clearing obstruction in pelvis, treating Agnimandhya at Jatharagni,Dhatwagni level and alleviating Srotoavarodha and ultimately regularizing the Apana Vata. PCOD can be managed with Ayurvedic dietary management.
